I'm in the middle of a custom 1950 Buick project. It'll include a hopped-up Straight 8 and a chopped top (not easy on a fastback...).
I always wanted a 'kustom' since I saw my first chopped Merc. This one won't be fast (by my own definition), but it'll be a lot of fun, comfy, and really different.
I started with a cherry 32K mile original car. It should be really nice when I get done with it. Wide whites, steelies, skirts, '53 side trim, '54 headlight rings, Smitty's muffs, flamethrowers, etc. Really straight and jet black, of course...
After I finish the '50 Buick and my '65 LeMans road racer projects, I'm jumping into a chopped Model A Sedan I've been dreaming about forever. It'll have a 409-based engine with a bunch of carbs, and a stickshift trans. Gotta have cheater slicks on that one...
I'll have to sell one of 'em though. I want one cool hot rod, custom, and muscle car to attain my personal automotive nirvana. Then I'll just drive the wheels off them all...
